| 摘 要： | 对塞罕坝林场华北落叶松人工林标准地的平均木和优势木进行树干解析,通过11m、13m、15m地位指数级的72株平均解析木和36株优势解析木资料,对华北落叶松人工林的胸径、材积与年龄之间的生长过程利用6种数学模型进行拟合,从中选出最优模型,并对模型进行检验,得出结论:在建立生长模型时应分别不同地位指数级进行;不同的生长因子须选择不同的生长模型拟合才能达到最佳效果;通过适应性检验,各回归方程拟合良好。

| Abstract: | Both average and dominant timber trunk of standard plots of planted Larix principis-rupprechtii forest of Saibanba farm is analyzed.According to the data of 72 average analyzed timber and 36 dominant analyzed timber of position index grade at 11cm,13cm and 15cm respectively,the growth process among the breast diameter,volume and age of planted Larix principis-rupprechtii forest is matching with 6 mathematical models.The optimal model is chosen and examined.It reaches a conclusion that to set up growth model should be conducted at different position index grade;and different growth factors should be matching with different growth models so as to obtain optimal result.Adaptability test reveals that each regressive equation has better adapting effects. |
